12-Bit, 105-MSPS Analog-to-Digital Converter (ADC) - ADS5521
Datasheet
 

Description

The ADS5521 is a high-performance, 12-bit, 105MSPS analog-to-digital converter (ADC). To provide a complete converter solution, it includes a high-bandwidth linear sample-and-hold stage (S&H) and internal reference. Designed for applications demanding the highest speed and highest dynamic performance in little space, the ADS5521 has excellent power consumption of 571 mW at 3.3-V single-supply voltage. This allows an even higher system integration density. The provided internal reference simplifies system design requirements. Parallel CMOS-compatible output ensures seamless interfacing with common logic.

The ADS5521 is available in a 64-pin TQFP PowerPAD package and in an industrial temperature grade device.
